Vallejo Naval & Historical Museum

Vallejo Naval & Historical Museum offers five galleries on Vallejo and Mare Island history for about $5 per adult, so two admissions stay inexpensive for an indoor date. Seniors and students are about $3, and Family Free Day runs every third Saturday.

Weekday and Saturday hours are published on the museum site. Use the free third Saturday when budget is tight, or a regular paid visit when you want a quieter gallery pace.

Pair with a short downtown Vallejo walk after if energy remains. Keep expectations to a compact history museum, not a full-day attraction campus.
